Rolex Explorer II has been in the shadow of the elderly for many years, the aviation theme brother and GMT-Master. While GMT replica watches are designed for pilots and frequent aviation travelers, Explorer II is made for cave scientists exploring caves beneath the Earth’s surface. The original Explorer II fake model had a very special look, and its initial poor sales were mainly due to its peculiar target audience rather than overlapping with another watch in the Rolex lineup. The successor to Explorer II, the other model is based primarily on the GMT-Master series of watches, and its many similarities ultimately hamper the potential sales of Explorer II.
We can see several different reference versions in history. The Rolex Explorer II series watches are still more or less GMT-Master with a fixed 24-hour bezel and white dial options. However, the luxury replica Rolex has launched a new version of the Explorer II – its design is completely unique. 
The new Explorer II features a new movement – an unprecedented Rolex watch model – the movement 3187, with a larger 42 mm case. With 31 jewels, a blue Parachrom hairspring, a variable inertia balance and an added Paraflex shock absorber, the 3187 movement can be seen as an improvement to the 3186 movement, which is now available at Rolex’s current GMT-Master II range. Found in the watch.
Another important change is the separation of the reference 216570 from the contemporary GMT-Master II, which is the revival of its bright orange 24-hour hands – a feature borrowed from the original Explorer II. This stunning fake watch features a triangular 24-hour hand and a bright orange color, so cave explorers can easily distinguish between day and night while watching the watch in low light conditions.
Although relatively small, the white dial option, bright orange 24-hour hands and an extra 2 mm case diameter help to make the fake watch very different from Rolex’s GMT-Master II watch. Although the modern GMT-Master is very similar to the modern Submariner, the Explorer II is now a popular watch of its own design. It is not similar to any other replica watch in Rolex’s current lineup.
For decades, the Explorer II has been a forgotten brother and sister of the Rolex GMT-Master watch; however, in 2011 (40th anniversary), Rolex finally gave Explorer II a long-awaited upgrade. This great watch is a modern watch that completely encompasses its past and history without losing its vision as a modern timepiece.
